Slither Wing Ancient Moth

Trample, haste

Whenever Slither Wing attacks, it gets +1/+1 until
end of turn for each creature card in your graveyard.

At the beginning of your end step, if Slither Wing attacked this turn, exile up to one card from your graveyard. If a creature card was exiled this way, create a 1/1 red and green Insect creature token with haste.
